IMPROVEMENT IN BINDERS FOR SEWING-MACHINES.

Specification forming part of Letters Patent No. 121,356, dated November28, 1871.

To all whom it may concern:

Be it known that I, BERNARD GOLDSMITH, of Newark, in the county of Essexand State of New Jersey, have invented an Improvement in Binders andHemmers; and I do hereby declare that the following is a full, clear,and exact description thereof, which will enable others skilled in theart to make and use the same, reference being had to the accompanyingdrawing forming a part of this specification, in which- Figure 1represents a horizontal section of my invention. Fig. 2 is a top view ofthe plate from which my improved binder is formed. Fig. 3 is a frontview of the binder, and Fig. 4 an edge view of the same.

Similar letters of reference indicate corresponding parts.

My invention relates to the manufacture of sewing-machine hemmers andbinders; and it will be first hereinafter fully described and thenclearly pointed out in the claim.

A in Fig. 3 of the drawing represents the plate from which the binder isformed. The halves of each are alike, and each consists of anearlysemicircular main plate or body, a, and of a projecting tongue,I). In forming the binder the tongue is, on its narrow neck 0, turnedover the plate a, and then the rounded outer part of a is turned overthe tongue to form a lip, 61, as is clearly shown in Fig. 1. This plateA is provided with diagonal slots, as shown, to guide or insure thepassage of the material about the tongues b b. The halves of the binderare then carried one over the other, as in Fig. 5. The binding materialis inserted at the large end of the tongue under the neck of the same,and when drawn ahead is finally bent over the outer edge of said tongue,the lip d keeping it in place thereon The desired degree of gradualcontraction is obtained by the more or less oblique turn of the lip. Thebinder thus produced is absolute in its action, furnishing a sharp edgefor the turning of the material on the tongue I) and a guarding-surfacefor the guiding of the fabric by the lip d. This binder may also be usedfor hemmin g.

The device is secured to the bed of the machine by means of a screwthrough the slot in the shank D, and the forward end of this shank isprovided with a raised and notched projection, g, that overhangs thematerial passing under it, preventing its being misplaced beforereaching the needle-presser. The 'presser is to come up to the notchedpart g.

I am aware that a double-hemming binder is not new, nor do I claimbroadly a hemmer composed of a central tongue and overlapping surfaces;but

What I do claim, and desire to protect by Letters Patent, is

As an article of manufacture, the binder herein described and shown,provided with slots 0 and projection g, as and for the purpose setforth.
